Reproductibilité test–retest des mesures stabilométriques après reconstruction du ligament croisé antérieur du genou chez le sujet sportif

Objective

To define the 3 day interval test-retest reproducibility of stabilometric measurements in two- and one legged stance in sport subjects recently operated from a knee anterior cruciate ligament reconstruction.

Méthode

Ten subjects aged between 16 to 33 years (23 year ± 5); carried out at 15 days after the knee surgery two sessions to measure steadiness in two legged stance with opened and closed eyes; in one legged stance with opened eyes, in healthy and operated leg, with full knee extension and with 20 degrees knee flexion. The reproducibility was determined using the intraclass correlation coefficient and the standard error of measurement was calculated.

Results

In two legged stance and in one legged stance, knee in 20 degrees flexion, the 95% sway area and the average antero-posterior excursion of the centre of pressure are reproducible (ICC > 0,75).The stabilometric parameters are not reproducible in one legged stance, knee in extension.

Conclusion

The reproducibility of stabilometric parameters is good, in two and in one legged stance knee flexed at 20 degrees, to evaluate the postural progress after anterior cruciate ligament reconstruction.     

Prévalence de l'asthme chez l'athlète,influence de la discipline sportive et des conditions environnementales

Purpose – To assess the prevalence of asthma (PA) in competitive athletesMethods – PA was studied in 530 athletes of a regional to an international caliber (cross country-skiers, cyclists, alpine skiers and judokas) on the basis of a specific questionnaire and a reversible airway obstruction.Results – Classified from the lowest to the highest, the PA according to sport was the following : judo, cross-country skiing, alpine skiing, and cycling.Conclusion – These results confirmed the PA is low in athletes who hyperventilate moderatly and are usually sheltered from cold temperatures. Although the PA of skiers (16%) was similar to that reported by other studies the high proportion of allergic asthma (60–80%) suggests a profile different from that reported in this subpopulation by others i.e. non atopic “asthma skiers”. The greater duration of cold exposure in the alpine skier group despite lower ventilatory requirements may account for its greater PA compared to that of the cross-country skiers. Finally, the higher PA of the cyclist group may be explained by the conjunction between the hyperventilation, exposure to aerocontaminants and possibly to cold.
